Flash Location:
This species stayed primarily over the grassy areas of the meadow and were more prevalent in areas with more frog sounds. Without identifying the frogs it is hard to know if this is significant.
Male Flash Behavior:
Their flash was very fast with small darting motion. They stayed high up in the air and trees at the edge of the meadow.
